A Foreword from the BRAMM Board
The British Register of Memorial Masons was established in 2004 to improve the standards of memorial construction, installation and safety within the UK’s cemeteries and churchyards. Our supporting organisations have monitored and underpinned the development of BRAMM including industry training and appropriate qualifications to ensure BRAMM Registered Businesses and their qualified Fixer Masons are working to the current British Standard ~ BS8415. A BRAMM Registered Business should issue “A Certificate of Compliance” to confirm a newly constructed memorial meets the current standard. These certificates, if requested, are issued without charge. Recently, the BRAMM Blue Book has been reviewed to provide technical, constructional and safety information in line with the current BS8415:2018. In addition, all Memorial Masonry Companies wishing to be included on the BRAMM Register sign a formal declaration saying, ‘I declare that all materials used will comply with BS8415 and that fixers will become accredited in accordance with guidance issued by BRAMM’. This important level of certification gives security to both the Bereaved and the Burial Authorities. To ensure our industry standards are maintained we recommend the BRAMM Blue Book as a sound source of information and further reading.
BRAMM’s Supporting Organisations
Businesses registered with BRAMM are accountable to both the bereaved and the cemetery management. Work that is not compliant with BS8415 can be reported to BRAMM, who provide a service to cemetery management to assist in resolving such
matters. In extreme cases additional training may be required and/or offered to maintain industry standards.
The BRAMM register provides, without charge, access to a national data base of all registered businesses who confirm their intentions to work to the current BS8415. A registered business can only engage qualified fixer masons and ensure their work will be of
an appropriate standard. Registered cemeteries that endorse working to BS8415 and have adopted the free scheme will receive a BRAMM affiliated certificate for display in public areas demonstrating commitment to current industry standards.
Here at the Commonwealth War Graves Commission we are continually striving for excellence. The Commonwealth War Graves Commission endorses the maintenance of high industry standards and supports the work of BRAMM.
FBCA ~ The Federation of Burial and Cremation Authorities strongly recommends the adoption of the BRAMM Register by cemetery management and personnel. The BRAMM data base is straight forward to use and assistance is readily available if it is required. All work is carried out to the current BS8415 which is reassuring to both cemetery owners and bereaved families ensuring that the memorial is stable and safely constructed.
The approval of memorials in churchyards is part of the important role of the church in supporting the recently bereaved. It is generally delegated to incumbents on the understanding that they have access to good advice. The churchyard regulations
issued by the chancellor in each diocese provide guidance as to the design of memorials and the choice of an inscription; but they do not go into the relevant constructional details. The Ecclesiastical Judges Association is therefore happy to welcome this new edition of the BRAMM Blue Book as a comprehensive guide to the technicalities of erecting memorials in churchyards. It will be a valuable supplement to BS8415 and will hopefully minimise the need for the remedial works that can cause so much distress. We are pleased to commend it to parishes and cemetery managers throughout England.
Whilst it is in not within the remit of an Educational Awarding Organisation to endorse a particular industry’s standards, we can readily certify that we have worked in close partnership with BRAMM to develop their set of Memorial Masonry industry-based courses. In addition, we have been fittingly impressed with their high levels of professionalism, commitment and transparency throughout.

Introduction
The best tradesmen are always looking for ways of improving their practical skills and level
of job knowledge ~ BRAMM can assist. The information provided in the BRAMM Blue Book
offers an account of Best Practice for memorial installation and furthermore is a good
reference point for anyone developing their knowledge or preparing to take an associated
industry qualification.
The BRAMM Blue Book is also intended help ensure that Burial Ground Managers and
their staff understand fully the processes and procedures used by Memorial Masons when
fixing and re-fixing memorials in cemeteries and burial grounds. Using the correct materials
and methodology is an essential part of this trade and it is the responsibility of the fixer
mason to ensure their work meets the industry standards as laid out in the current BS8415.
(The British Standard for the Memorial Masonry industry)
It is clearly understood that there are many different ways of compiling with the current
BS8415 when erecting a memorial. However, following the BRAMM Blue Book’s easily
understood recommendations, diagrams and guidelines will ensure the requirements of the
current BS8415 will be achieved by competent memorial fixer/mason tradesmen.
Permission to reproduce extracts from BS 8415:2018 is granted by BSI. Copies of current
British Standards can be obtained in either PDF or hard copy format from the BSI’s online
shop: www.bsigroup.com/Shop or by contacting BSI Customer Services for hard copies
only: Tel: 020 8996 9001 ~ email: [email protected].
BS8415 is the industry’s definitive Standard. It must be clearly understood that the rationale
behind the BRAMM Blue Book is not in any way to take the place of BS8415, or indeed any
similar publications; its primary aim is to offer a helpful reference guide and easily
understandable document to support both Memorial Fixer/Masons and Cemetery Personnel.
Wherever practicable, BRAMM have used plain English and simple line drawings in the
explanation narrative, Page layout and production of the Blue Book. In addition, metric to
imperial conversions are rounded up/down to the nearest ½” and follow the metric
measurements to aid familiarisation.
BRAMM Memorialisation Education & Training
For the benefit of Memorial Masons and those responsible for Managing Churchyards and
Local Authority Cemeteries, BRAMM run three education and training courses which are
underpinned by the Open College Network (West Midlands).
The suite of three separate courses falls under the overarching ‘BRAMM Memorialisation’
umbrella and consists of 3 separate Units:
Unit 1 ~ Installation of Lawn and Monolith Memorials
Unit 2 ~ Advanced Fixer Mason
Unit 3 ~ Memorial Inspections – Assessments – Actions* *Pending accreditation ~ please contact BRAMM for further information.

Memorial Design & Construction Considerations
All memorials over 625mm (24.5”) in height should be designed and installed in compliance with the current BS8415. They are required to be constructed to withstand a force of 70kg applied at the apex of the memorial or at 1500mm (59”) from the ground, whichever is the lower.
The British Standard is a performance specification that requires memorials over 625mm (24½”) in height to be constructed to withstand a force of 70kg. Note that the pressure is nearly triple the force that the memorial and its components may be subjected to for stability test. In the Cemetery, any subsequent test pressure should not exceed 25kg.
Memorials over 625mm (24½”) in height: When using an independent foundation slab for a memorial, the slab should be wider than the grave so it sits on virgin ground and be made from pre-cast reinforced concrete or a suitable hard stone. BRAMM also recommend that a lawn memorial foundation should be wider than the memorial’s base and, if possible, a little deeper front to back (depending on the cemetery’s R&Rs) to facilitate both aesthetics and a more even weight distribution. This will also help to prevent the possibility of accidental mower damage to the memorial’s base during cemetery ground maintenance procedures.
In all cases the base must be fixed to the foundation using a recognised and accredited memorial anchorage system, compliant dowels or a recognised memorial locking system.
The requirements are achieved by ensuring that all parts of the memorial are able to withstand the forces required.
Important: The following items should always be taken into consideration when constructing the memorial to ensure it achieves the performance requirements of BS 8415.
1) Ground conditions.
It is the responsibility of the fixer mason to ensure the ground conditions are suitable for the selected fixing method.
The minimum front to back dimension of undisturbed ground to permit proper fixing for a lawn type memorial shall be 600mm (23½”) at the head of the grave ~ see Page 38. The Burial Authority shall ensure that their grave digging practices meet this standard.
If the Burial Authority has been unable to provide 600mm (23½”) of undisturbed ground at the head of the grave then every effort should be made to use a foundation of sufficient length, depth and width so as to support the memorial on undisturbed ground.
2) Foundations and Foundation Design
It is essential that memorial foundations, either pre-cast or cast in situ, shall be designed in accordance with sound engineering principles having regard to the size and load/weight imposed by the memorial and the foundation’s reinforcement must meet the current BS8415 standard.
In addition, local soil conditions, possible foundation movement and any special requirements shall be considered in the foundations design. Foundations shall be level on both axes with drainage provided to resist water accumulation within the structure.

It is the purchaser of the foundation who should ensure the foundation is fit for purpose. The fixer masons should also be aware that a foundation design and reinforcement must meet the requirements of the current BS8415. (Page 27)
No actual size of individual lawn memorial foundation is stipulated in BS8415 but, for
standard HS&B lawn memorials, BRAMM strongly recommend the MINIMUM size should be 900mm x 450mm x 75mm (36” x 18” x 3”) for suitably reinforced concrete and/or granite or hard stone foundations slabs. (See Page 33) Note: The foundation size must meet the requirements of the ground anchor manufacturer where appropriate. In addition BRAMM recommend, wherever possible, that the foundation slab should be
larger in footprint in both ‘side-2-side’ and ‘front-2-back’ axes dimensions than the memorial’s base to distribute the overall weight over a wider area.
Trough or ‘knock-out’ foundations must NOT be used as per BS8415:2018. Large or
multiple holes in pre-cast concrete foundations for flower containers reduce contact area’s strength and must be kept to a minimum as clearly stated in BS8415:2018.
4) Assembly
Stainless steel dowels, minimum grade A2 or A4, shall be used between all components; the minimum sizes are illustrated on Pages 8 to 20.
It is recommended that as small memorials, i.e. less than 625mm (24.5”) in height are not covered by the structural requirements of the British Standard, they should, as a minimum, be dowelled to their foundations in compliance with the specified dowel and dowel hole sizes for the plate to base joint which can be referenced on Pages 8 to 20.
Where possible, a mechanical means of securing the base to the foundation should be adopted. However, if the memorial is made from 50mm (2”) material it is possible to have suitable dowels from within the plate, through the base and into the foundation.
Memorials of 625mm (24½”) and above must have either an accredited ground anchor, an approved mechanical locking system (often referred to as a ‘lock-downs’) or be dowelled to a suitable foundation.
It is essential to always work to the ground anchor and/or mechanical locking
systems manufactures specifications and/or to contact them for further advice if necessary to ensure compliance with the current BS8415.
All holes for the ground anchor in the foundation and memorial base/sub base must not exceed those directed by the ground anchor manufacturer’s specifications.
If a sub-base is used with a lawn memorial construction, it is important to ensure the length of the anchor is correct for this use ~ refer to the manufacturer’s specifications.
The experienced fixer mason will know the memorial installation process is often determined by seasons and/or weather conditions. Cement has many known limitations and the fixer may chose to avoid the use of cement when there is greater possibility of
rain, frost, snow or stormy weather. Alternatives such as mechanical locking systems and, in some limited circumstances, industry tested adhesives may be considered.

5) Joints
Joints shall be constructed as tight as practicable. Any item that could otherwise act as
a spacer, i.e. nuts or washers, should be countersunk into one of the adjoining parts.
6) Ground Anchors
There are numerous ground anchor systems available. Information regarding ground
anchors and their usage is available from each manufacturer and/or supplier together
with evidence of their specifications and product testing results.
Before using a system it is essential to carefully read the manufacturer’s instructions to
ensure that the chosen anchor is the correct size for the memorial and it is correctly fitted.
If fixing on sandy soil or on steep slopes where thicker memorial foundations are being
used, the ground anchor manufacturer should be consulted for guidance on length and
diameter of ground anchor to be used.
Ground anchors are designed to be used on single/multiple foundations, poured
foundations and for use with a sub-base or, where necessary, a support bearer. The
ground anchor manufacturer will be able to advise wherever necessary.
7) Selecting a Ground Anchor
BS8415 requires a ‘Rigid’ type of ground anchor system (for use mainly with granites
and hard stone) to withstand a force of 150kg for 1 minute whilst a ‘Progressive Failure’
system (specifically suitable for softer or weaker stone) is required to withstand a force
of 100kg for 1 minute. See both the ground anchor manufacturer’s instructions and/or
specification sheets for the correct usage and more detailed information.
8) Ground Anchor Manufacturers’ and Users Responsibilities:
a) It is the responsibility of the Ground Anchor Manufacturer to ensure their products
are tested in accordance with both their printed specifications and BS8145:2018.
b) It is the responsibility of the fixer mason to select an appropriate anchor system and
to ensure it is used in compliance with the manufacturer’s instructions.
9) Soil Types ~ Ground Anchor testing (to meet BS8415:2018) will be carried out in
medium sand and gravel. It follows therefore that the new testing procedures will ensure
ground anchors provide suitable resistance in all soil types.
Note: When reinstating a memorial with a previously installed
ground anchor, the fixer mason should seek confirmation from
the manufacturer that the system previously used meets the
current requirements of BS8415:2018.

Dowels, Dowel Holes & Their Usage
Dowels are a traditional means of fixing in the memorial industry and, with
lawn memorials, can be used for plate to base, base to sub-base and
base to a suitably reinforced concrete or granite or hardstone foundation.
In each case, dowels must be secured by cement paste or suitable resin. All dowels used in
a memorial’s construction MUST be made from either A2 or A4 grade stainless steel.
The correct dowelling and dowel-hole Ø requirements differ slightly depending on the lawn
memorial’s material and size. If the memorial’s material is Granite, Hard Limestone, Marble
or Slate there are slightly different specifications to be followed from those if the material
being used is General Limestone and/or other types of softer stone.
In most instances, the ‘Rule of Thumb’ dowel-hole size is: Ø of dowel + 4mm for the dowel
holes in the plate and + 8mm Ø for the dowel holes in the base. Example: When using
16mm Ø dowels you would need 20mmØ holes in the plate and 24mmØ holes in the base.
The following index and illustrations will help clarify the specification differences visually.
It is most important to bear in mind that the dowel lengths and dowel engagements shown
in the illustrations are MINIMUM lengths and engagements.

In all cases, a maximum clearance of 4mm in memorial plate dowel hole and 8mm in base
must be maintained. Larger diameter dowels can be used to achieve this. This applies to
Fig 1, Fig 2 and Fig 3
Fixer masons may find it easier to use a 250mm (10”) x 20mm dowel to ensure a 100mm

Note: Very Large Memorials heavier than 4t (4 metric tonnes = 3.9 imperial tons)
All memorials with a mass greater than 4t excluding any foundations are required to be
specially designed by a structural engineer or architect and have drawings submitted to the
burial authority for authorisation prior to the commencement of any work.

Book to Tick Rests: Threaded dowels MUST be used ~ minimum of 12mmØ and a minimum
50mm (2”) in length fixed and set 25mm (1”) into each component in the workshop.
Tick Rests to base: Dowels 16mmØ x 150mm (6”) and a maximum clearance of 4mm in the
tick rest’s dowel holes and 8mm in base’s dowel holes must be maintained.
If the memorial’s overall height is below 625mm (24.5”) dowels may be used to secure the
memorial’s base to its foundation. See the dowel size information on Page 9.
If the memorial’s overall height is above 625mm (24.5”) an accredited ground anchor
system must be used or, if preferred, a compliant memorial locking system may be used to
secure a book set to its foundation subject to the system manufacturer’s instructions.

Securing Lawn Memorials to their Foundations
There are three main methods of securing lawn memorials to their foundations:
a) An accredited/approved Ground Anchor
b) Dowels ~ as plate to base specification
c) Mechanical locking systems (not illustrated ~ please see notes below)
Mechanical Locking Systems
There are several mechanical locking systems (often referred to as ‘lock-downs’)
available for the fixer mason to use depending on the type of fixing to be carried out.
Mechanical locking systems are a ‘cement free’ fixing method used to fix a lawn
memorial to its foundation after its plate and base have been bolted together.
Typically, the plate/base assembly is ‘bolted’ (or locked-down) to its foundation and, once the bolt is correctly tightened, the memorial is held firmly in place.
It will be appreciated that mechanical locking systems will usually make subsequent removal easier for perhaps any renovation work or perhaps for a further inscription.
It is the mason’s responsibility to ensure the mechanical locking system chosen has a current Manufacturers Specification Sheet, Instructions for Use and is accredited
to BS8415:2018 standards.
Cast In-Situ Concrete Poured Foundations
The following list is a recommended guide to the necessary minimum specifications,
a) The pre-poured lawn memorial foundation’s excavation size must be
a minimum of 900mm (36”) wide x 375mm (18”) front to back and
370mm (14.5”) deep wherever possible. Any water ingress must be
pumped out of the excavation before the concrete is poured.
b) The sides of the excavation must be perpendicular and its bottom must be flat.
c) The concrete mix must follow the mix ratio recommendations on Page 26 of the
BRAMM Blue Book with appropriate reinforcing added during the pouring process.
d) Pouring must have been completed at least 14 days before the memorial’s
installation to allow the concrete sufficient time to cure (set) properly.
e) The top surface of the foundation must be trowelled smooth, level and well finished.
f) The memorial must be either dowelled to the pre-poured foundation following the
Blue Book’s guidance or fixed using an accredited ‘lock down’ anchor system.
g) A mechanical locking system will make subsequent removal easier.

Full Grave Memorial Foundations
Full grave traditional memorial foundations are
many and varied and depend largely on the
memorial’s design, its overall size and weight and
the destination cemetery’s ground conditions.
Purely as an example, and in its simplest form, a
typical single width full grave memorial foundation would comprise of a one-piece
reinforced concrete frame landing similar to the example shown above.
Note: Manufactured foundations must be reinforced to meet the standards of both BS8415
and BS4449. It is the responsibility of the fixer mason to acquire the evidence that the
proposed foundation is manufactured and reinforced to the aforementioned standards.
Frame landings may require additional support if necessary depending on the ground
conditions ~ two examples are shown on the following page. As with most traditional full
grave memorial foundations, the footprint should be larger than the memorial itself.
Again, purely for example, the fixing of a standard headstone and three kerbs set using
75mm (3”) material in its simplest form would follow the diagram below:
1 ~ Ground Level
2 ~ 16mmØ x 150mm (6”) dowels engaging 75mm (3”) into both plate and frame landing.
3 ~ 150mm x 75mm (6” x 3”) kerbing.
4 ~ One-piece reinforced concrete frame landing which must be a minimum of 75mm (3”) thick.
5 ~ Minimum 10mmØ x 75mm (3”) dowels engaging a minimum of 37mm (1½”) into the adjoining material.

Examples of Additional Frame Landing Support
There may be occasions where a reinforced frame landing used on its own requires some
additional support to help ensure its long term stability.
Generally speaking, these occasions usually fall into one of three categories:
a) On steeply sloping cemetery ground
b) On softer, sandy cemetery ground
c) On spongey cemetery ground with a high water table
Either of the following additional supports may be used if necessary:
1) Reinforced concrete or hard stone bearers spanning the maximum width of the burial
plot to make full use of the support given by undisturbed ground.

The set on the right shows part of a standard Latin cross, three die (sometimes known as blocks or bases) and kerb set.
A single, centre dowel is used in conjunction with a shorter locating peg used in order to prevent the cross twisting on the centre dowel.
The centre dowel should be fully cemented and the locating peg may be fitted dry but must be a minimum of 10mmØ.
The bottom die must have a suitable support block or support pillars under it so the cross and die’s combined weight is not taken by the memorial’s side and head kerbs.
These do not need the same material as the rest of the memorial if they won’t be seen when the memorial is complete.
However, they must be dowelled to both the bottom die and the memorial’s foundation.
Wall plaques should be supported by
appropriate corbels and fixed to the
vertical surface using suitably sized
stainless steel fixing pins which should
slope at least 10° from the horizontal.
It is considered Best Practice to point up
only the top and side joints where the
plaque meets the wall to prevent any
ingress from water, grass seeds, etc.
Should there be any ingress, it will drain
away via the un-pointed bottom joint.

Cement
Health & Safety issues when using cement.
Cement is commonly used in the memorial industry but all too often its users are not fully
aware of its Health & Safety issues.
PPE (Personal Protective Equipment)
The correct PPE should be fit for purpose and worn when using and mixing cement as it
can cause dermatitis and damage to nerve endings. Wet cement when in contact with the
skin can cause an alkaline burn. Cement contains liquid chromium which can cause nerve
endings damage. When mixing cement avoid breathing in the dust as it is carcinogenic so
always protect yourself with suitable gloves, a dust mask and eye protection when mixing.
General guidance
It is important to remove air from a joint. This is usually achieved by working the surfaces
together. This will maximise the grip between the joint’s surfaces and will prevent ‘voids’
were water may collect, freeze and possibly expand and fracture the joint.
All surfaces where cement paste is used should be “keyed” to give better adhesion.
Ensure there are no entry points for rain water to access the joints.
Trough slabs are no longer allowed as their troughs reduced the contact area for
the cement and, as a consequence, resulted in a weaker joint.
All flower container holes should have sufficient clear drainage to the sub-soil.
If cement has been used to construct the memorial, the structure should not be tested for
stability for at least 28 days ~ i.e. the minimum curing time of the most types of cement.
Tried and tested methods of using cement.
Prepare the memorial for installation.
The mixing of cement should be carried out immediately prior
to its use.
Only mix enough cement for the proposed work to be carried out.
The cement should be thoroughly mixed to a thick, creamy ‘yoghurt-like’ consistency to
achieve best results.
Note: In the memorial industry, masons generally use neat cement, which is mixed with
clean water into what memorial masons refer to as a ‘cement paste’.
-
P a g e | 26
Once mixed to the right consistency a chemical reaction begins.
If the cement begins to dry out a little before use DO NOT add additional water. By adding more water the cement’s chemical reaction will be changed and the strength of the cement
will be adversely affected.
All surfaces to be joined should be clean, dust free and well damped with clean water before the cement is applied in order to prevent cement drying too quickly and causing hydraulic shock.
If the temperature is likely to fall below 5° centigrade during the initial 28 day curing period a suitable frost proofing cement additive should be used ~ see Page 29.
Any excess or unused remaining cement mixed must be taken off-site and disposed of in compliance with the current COSHH Regulations.
Storing cement
Cement has a defined ‘shelf life’ because of the trace elements it contains.
When buying Cement always check the ‘use by’ date before purchase.
The cement bag should have a CE mark which will confirm the product is manufactured to the current BS EN 197-1 standard.
BS 8415 requires the fixer mason to use Cement 1 or 2 which will be marked on the
cement bag.
Cement 1. This is generally known as ‘Portland Cement’. This product achieves a higher strength in the early stages of setting (curing). Cure time 28 days.
Cement 2. This is readily available from most builders’ merchants. Cure time 28 days.
Concrete used for Memorial Foundations
BS8415 has three basic requirements to ensure reinforced concrete foundation compliance.
1. The concrete used in the foundations of memorials within burial grounds and memorial sites shall conform to the current BS EN 206 -1.
2. The characteristic compressive strength of the concrete at 28 days shall be not less than 30 N/mm2. (For clarity, 30 N/mm2 is equivalent to 4351psi)
3. The reinforcing steel used in the concrete foundations of memorials within burial
grounds and memorial sites shall conform to the current BS4449.
Concrete must be thoroughly and carefully mixed using clean water and the following ratio: 1 x Cement ~ 2 x Sand ~ 4 x Aggregate
Great care must be taken to not make the mix ‘too wet’ as to do so will have an adverse effect on both the concrete’s curing time and its long term integral strength.

Reinforced Concrete Memorial Foundations
Part of the Registration Process of a Memorial Masonry Company wishing to be listed on
the BRAMM Register is a declaration on the Application Form in which the applicant
certifies that all the materials used by the Company will comply with the current BS8415.
The information below has been included in the BRAMM Blue Book both for the sake of
clarity and as a useful aid to a BRAMM Registered Company wishing to ensure they are in
full compliance with BS8415 with the reinforced concrete memorial foundations they use.
BS8415 has three basic requirements to ensure reinforced concrete foundation compliance.
1. The concrete used in the foundations of memorials within burial grounds and memorial sites shall conform to the current BS EN 206 -1.
2. The characteristic compressive strength of the concrete at 28 days shall be not less than 30 N/mm2. (For clarity, 30 N/mm2 is equivalent to 4351psi)
3. The reinforcing steel used in the concrete foundations of memorials within burial
grounds and memorial sites shall conform to the current BS4449.
These three images show the correct steel reinforcement (known as
‘Rebar’) and its usual positioning within a typical reinforced concrete
foundation for both a standard lawn memorial and a traditional kerb set.
Please Note: Fibre reinforced concrete memorial foundations without rebar DO NOT
comply with the current BS8415.
All ground anchor holes, whether precast or cored at
a later stage, must be the correct diameter for the
proposed ground anchor to be used. The minimum
‘front to back’ depth of the foundation slab must
correspond to the accreditation of the ground anchor.
BRAMM always recommend using the largest foundation slab allowed in the burial ground
to give a greater spread to the memorial’s weight and reduce the likelihood of settlement.

The Bolting System
The epoxy resin used to secure studs (the construction industry’s correct term for threaded
dowels) into a lawn memorial’s plate must be as recommended by the manufacturer as
suitable for use in the memorial industry or that has a proven suitability within the stone
construction industry.
The bolting together of components is usually carried out in the mason’s workshop and a
suitable membrane, e.g. damp-proof course material or similar product, MUST be used to
cover the entire area between the headstone’s plate and base to help limit water ingress.
The wet cored holes in the plate must be clean, dust free and, if necessary, suitably keyed
to give good adhesion to the epoxy resin which will firmly hold the dowels in place.
Bolting memorial parts together has been proven to achieve the necessary standards using
sizes as shown in the table below.

1221mm – 1830mm 16mm 150mm (6”) 90Nm (65 ft/lbs)
*Refer to Pages 8 to 20 regarding the size of dowel holes in the inscription plate.
A single stainless steel washer must be used under the nuts. The washer must
be minimum 3mm thick and of a diameter of at least one and a half times the
diameter of the base dowel hole, e.g. a 30mm washer for a 20mm hole.
Important:
a) Great care must be taken to apply the correct torque and not over-tighten the nuts.
b) It is important for the torque wrench
used to be regularly calibrated to
ensure its accuracy is maintained.
c) The nuts used in the Bolting
System must be ‘Locking Nuts’ ~
e.g. spring washers, lock-tight nuts.

P a g e | 29
MS Polymers & Flexible Bonding Agents
In some limited circumstances, MS Polymers and/or Flexible Bonding Agents may be used to join granite and stone to each other or to concrete.
As with using any form of adhesive, including MS Polymers or Flexible Bonding Agents to join granite and/or stone to concrete surfaces, it is essential that all surfaces are
dust free and thoroughly cleaned off to ensure any salts and/or releasing oil is completely removed to help ensure good adhesion.
A vigorously applied good quality wire brush is essential for this work.
However, be aware that regarding flexible bonding agents, BS8415 says, ‘Performance class specified in BS EN ISO 11600, accompanied by manufacturer’s guarantee that the product is fit for external use with natural stone, granite or marble and its curing temperature is suitable to the UK climate.’
Obviously, the manufacturer’s instructions must be followed to the letter at all times.
Note: Epoxy Resin is the adhesive to be used when securing dowels into stone, e.g. into a lawn memorial’s inscription plate when using the Bolting System - NOT MS Polymers.
Use of Cement Additives
Cement additives are usually designed to make working with cement easier and help to produce better results.
For example, in very hot weather a cement mix may dry out too quickly and cause fine ‘hair cracking’ in the cement which will weaken it and allow water ingress.
Conversely, in very cold weather, the mix may dry out too slowly which will result in a weak joint and could even lead to the joint having permanent frost damage!
Cement additives can go some way to helping to prevent these problems.
However, it is generally accepted Best Practice to try and avoid using cement wherever possible if the ambient temperature in the cemetery or churchyard drops below 5ºc.
Important Fixing Considerations
Preparation prior to transportation of a memorial
It is Best Practice, but not mandatory, for the fixer mason to have a correctly stocked First Aid Kit in his vehicle at all times.
All materials, tools and equipment should be safely secured to protect them against movement damage during transportation to the destination cemetery or churchyard.
Ensure that others know where you are working and how long you are likely to be away.
A fully charged mobile phone is essential item in case of emergencies. See also the HSE guidance on ‘Working Alone’ ~ http://www.hse.gov.uk/pubns/indg73.pdf
http://www.hse.gov.uk/pubns/indg73.pdf
-
P a g e | 30
Documentation
Fixing permits, local fee payments (where applicable) and all cemetery or churchyard authorisations must be completed and approved before an installation takes place.
Fixer masons must always familiarise themselves and fully comply with the Rules and Regulations of the cemetery or churchyard they propose to work in.
Risk Assessment in the Cemetery
It is mandatory to carry out a visual risk assessment when arriving on site. However, if you find a potential hazard you are required to carry out written site specific risk assessment and implement the necessary control measures. This is known as a Site Specific Risk Assessment and covers the working area and its approach route. Included are those carrying out the memorial’s installation and anyone else who may be in or near the working area such as passing members of the public, cemetery staff and other fixer/masons.
Preparing the site for the memorial installation
Define the working area using road cones, road pins and tape or suitable signage to help create a safe and secure area in which to work. Decide where tools and waste materials will be placed and how the memorial and its components will be moved and positioned for installation.
Installation Objective
To ensure the installation of the memorial meets BS8415 and is in line, level and plumb with the aid of a string line and a spirit level.
During the Installation
Should a funeral cortège arrive in the vicinity of the working area, all installation work should cease and any mechanical or electrical equipment should be switched off until both the cortège and all the funeral’s mourners have left the cemetery.
Leaving the Cemetery or Churchyard
Ensure that both the installation and its surrounding area are left in a clean, tidy and safe state and that no tools or equipment, spoil, etc. have inadvertently been left behind.
Report your departure to the cemetery or churchyard office if required.
It is also Best Practice to report any dangerous memorials to the cemetery or churchyard office together with your own office so everyone is aware and forewarned aware of the potential hazard.

P a g e | 31
Re-fixing/Re-installing Memorials
If needing re-fixing, all memorials must be re-fixed to the current BS8415 standard.
As an example, if a lawn memorial has to be re-fixed after being deemed to be dangerous or perhaps following the addition of a further inscription, it must be re-fixed in compliance with the current BS8415. However, in some instances the memorial plate may not need to be removed from its base. In these circumstances the fixer mason has no knowledge of the integrity of the joint and/or the dowels and whether or not it/they comply with BS8415?
In such circumstances, the mason must core through the base into the plate and secure the base to the plate using dowels and cement or an approved resin. It is advised that a 20mm core drill is used with 16mm dowels. With a standard size lawn memorial the dowel holes must be of sufficient depth to allow dowels at least a 75mm (3”) engagement into the plate.
It is also necessary to check the memorial’s ground anchor and foundation to ensure they both are compliant with the BS8415. If in any doubt whatsoever ~ always replace both.
Fig 10 ~ Re-fixed Lawn Memorial ~ Example Shown: Overall Height 900mm (35.5”) using 100mm (4”) material

Ground level BS8415:2018
Note: Ground anchor fixing will be achieved
by drilling the appropriate size hole in the
memorial base and using the correct size
foundation with correct size anchor hole in
compliance with the anchor manufacturer’s
instructions.
Note: A mechanical method (or lock-down)
can be used to secure a standard lawn
memorial to its foundation but an approved
ground anchor must still be used. See
Page 21 for further information.

BRAMM Supplementary Information
Health & Safety requirements:
The Health & Safety at Work Act 1974 places a legal duty on all people at work. Under the act it is the responsibility of all concerned to ‘ensure their own safety and that of others’ in the workplace ~ which of course, in our case, includes cemeteries and churchyards. It is important to view and understand your employer’s Health & Safety policy as it explains how your health and safety is managed. PPE is supplied by employer and must be used, worn and/or maintained as necessary. Rubbish or other materials left over after fixing it should be gathered up and either removed from the site or placed in on-site designated areas.
Work place accidents must be reported to the cemetery office and also be recorded in the company’s Accident Book. Care should be taken when using adhesives and other substances. Always follow manufacturer’s specifications for
their correct usage. A correctly stocked First Aid Kit should be available in the workshop and, whilst not mandatory, in the fixer’s vehicle in case of an emergency whilst out on-site.
Risk Assessments
A thorough Site Specific Risk Assessment will reveal any possible risks or hazards which may affect safe on-site working. Each business should have relevant Risk Assessment documentation and memorial fixers need to carry out on-site risk assessments prior to carrying out a memorial installation. Risks or hazards may come from people, equipment and/or the environment. Control measures must be decided upon and implemented before the commencement of any work.
Memorial design requirements
Refer to Page 6 for the main criteria. All metal used in the construction of a memorial must be stainless steel conforming to BS6744 Grade A2 or A4. Installation of Monolith memorials require a minimum of 25% of the memorial (including its foundation) to be installed below ground level. Monolith memorials are frequently installed into a reinforced concrete or hard stone shoe to increase their long term stability. See Page 17 of this BRAMM Blue Book.
Pre-cast Concrete, Hardstone and Granite Lawn Memorial Foundations
Note: Manufactured foundations must be reinforced to meet the standards of both BS8415 and BS4449. It is the responsibility of the fixer mason to acquire the evidence that the proposed foundation is manufactured and reinforced to the aforementioned standards.
Reinforcement: BS8415:2018 references indicate that metal reinforcement should be used in the manufacture of pre-cast concrete memorial foundations and anchor holes should be supported with suitable reinforcement.
When purchasing reinforced pre-cast concrete foundations, the mason must firstly consult the foundation manufacturer to confirm that their foundations fully comply with the current BS 8415:2018 recommendations for the reinforcement of pre-cast foundations.
Trough foundations are NOT permitted and multiple flower container holes in pre-cast
concrete foundation slabs should be kept to a minimum as clearly stated in BS8415:2018.
-
P a g e | 33
As no specific individual lawn memorial foundation size is stipulated in BS8415, BRAMM recommend the following MINIMUM foundation size for standard type lawn memorials up to 915mm (36”) in overall height:
Reinforced Concrete: (Refer to Page 28) 900mm x 450mm x 75mm (36” x 18” x 3”)
Hardstone (density must be at least 2400 kg/m³) 900mm x 450mm x 75mm (36” x 18” x 3”)
Granite (density must be of at least 2650 kg/m³) 900mm x 450mm x 75mm (36” x 18” x 3”)
For lawn memorials exceeding 915m (36”) in overall height, BRAMM recommend the use of a larger, more substantial foundation help distribute the additional weight more effectively. One way to achieve this is to use a larger, thicker and deeper bespoke foundation slab to provide greater integral strength and additional load bearing capacity. Ideally, these larger slabs should be the maximum width allowed in the cemetery so that as much of the weight as possible is supported on virgin ground. If in doubt, seek professional advice from your foundation manufacturer. In extreme cases, a pre-poured concrete foundation (Page 21) may possibly be allowed, but this would depend on the cemetery’s Rules & Regulations. Also, bear in mind that with larger lawn memorials you will have to increase the ground anchor specifications ~ check with your anchor manufacturer to ensure BS8415 compliance.
Important Note: It is strongly recommended that all individual lawn memorial foundation slabs should have a minimum depth (front to back) of 450mm (18”) or meet the chosen anchor manufacturer’s requirements as shown on the Anchor Manufacturer’s Accreditation Specification and/or its Instructions for Use Sheets. The slabs should also be wide enough to ensure they span the grave with as much of it as possible to rest on virgin ground.
Many lawn memorial foundation slab manufacturers supply their foundation slabs with three ‘ground anchor style’ holes already in place as shown in the illustrations above. This allows the fixer to use the same slab for either the Bolting Method or the Cement & Dowels Method to fix a lawn memorial. If using the Bolting Method to fix the memorial’s plate to its base, the washer, nuts and any excess length of threaded dowels are accommodated within the two outer holes with the centre hole being used for the chosen ground anchor.
However, if the lawn memorial is to fixed using the traditional Cement & Dowels Method there is a real possibility of the dowels being pushed, or even slipping, downwards into the ‘void’ in the foundation slab below the dowel holes in the lawn memorial’s base designed to ultimately contain the fully cemented dowels. This risk is exactly the same if the dowels are pre-cemented into the plate prior to the plate being offered to the base as the dowels may well push the cement in the base’s dowel holes down into the void in the foundation slab.
It is critically important to understand that, if either suggested scenario should occur, it would make the lawn memorial’s fixing non-compliant with BS8415:2018.
Where there is a possibility of this happening, the two outer holes in the foundation slab must be carefully filled in or plugged flush with the overall surface of the foundation slab to prevent this non-compliant situation from occurring.

P a g e | 34
Lawn Memorial Foundation Preparation
Soil should firstly be properly prepared, vigorously rammed and tamped (firmed and consolidated) with a suitable heavy metal rammer as shown on the left before the pre-cast reinforced concrete, hardstone or granite foundation slab is carefully positioned as it helps to ensure the memorial’s long term stability. Sharp sand can also be used as a fine levelling agent.
All spoil removed must be placed on a tarpaulin or in a wheel barrow to protect the surrounding turf from any damage and ultimately removed.
Linear Raft or Strip Beam reinforced pre-cast concrete foundations must be a minimum of 150mm (6”) thick and correctly stepped if used on sloping ground. (See Page 18)
Individual poured block foundations require a mix of concrete to a ratio of 1 x cement, 2 x sand and 4 x aggregate with appropriate reinforcement used. The foundation should be allowed to cure (set) for at least 14 days before proceeding with the memorial’s installation. See Page 21 for more information on individually poured block foundations.
It is appreciated that it is usual practice for the memorial mason to supply and install the individual foundation slab as part of a lawn memorial’s overall installation. However, some Burial Authorities provide, and even install, their own foundation slabs and insist that the memorial mason fixes to them. These foundation slabs should always comply with the current BS8415 and the relevant information should be given in the Burial Authority’s written Rules & Regulations. In such cases the Burial Authority must accept full responsibility for the foundation they supply in terms its stability, longevity and specification.
Memorial Inspection, Assessment & Action
It is most important for those in charge of the management of Churchyards and Local Authority Cemeteries that they have a written policy in place (as stated in BS8415:2018) to cover the safety inspection and assessment of existing memorials within their premises.
Broadly speaking, and ideally, satisfying the need to make sure all memorials in their burial sites are in a safe condition and the risk to anyone on-site is minimized.
This is covered by the Ministry of Justice under their ‘Duty of Care’ umbrella ~ it is therefore a legal requirement and is, as aforementioned, supported by BS8145:2018.
This policy must cover everything from the initial decision to carry out a memorial inspection scheme through to having a suitable exit strategy for the completion of the project.
There are a number of important considerations to be addressed with pre-planning being the most important part of the whole process. A non-exhaustive list would cover:
a) Generating the necessary paperwork and ancillary documentation.
b) Effective communication with the local community and other bodies who may be
involved to obtain their understanding and support.
c) Prioritising the burial areas within the burial ground which are most at risk.
d) Setting realistic time scales and budgets for the tasks to be carried out.

f) Organising for competent and qualified contractors to undertake the task.
g) The importance of avoidance of any perceived conflict of interest between those
carrying out the inspection and assessment and those carrying out the necessary
actions to re-instate any unsafe memorials.
h) Formulating a workable, satisfactory and fully understood exit strategy.
i) Record keeping and arrangements for ongoing inspections.
BRAMM can offer advice to Memorial Masons and Churchyard or Cemetery Managers.

Glossary
Arris A sharp edge, created when two surfaces meet.
Burial Authority (BA) An organisation responsible for managing a burial ground.
Cement A fixative used to secure dowels into the cored or drilled holes in the
memorial and/or foundation. Note: Threaded dowelling (studs) used in the
bolting system must be fixed in the plate using a suitable Epoxy Resin.
Chamfer Where two surfaces meet the corner is removed to create a flat surface
joining the two existing surfaces.
Dowel A stainless steel pin to align, prevent movement and make a secure joint
between adjacent elements of a memorial.
Epoxy Resin The adhesive used when securing dowels into stone, e.g. into a lawn
memorial’s inscription plate (headstone) when using the Bolting System.
Foundation A part of a structure in direct contact with and transmitting load to the
supporting ground.
Ground Anchor Typically, a long stainless steel bar driven through the foundation in order
to pin it to the ground thus providing stability. Several approved ground
anchors are available and are currently being used by Memorial Masons.
Hydraulic Shock This is a term used when cement is applied to a dry surface. Water will
quickly be drawn from the cement mix altering the chemical reaction.
Cement suffering hydraulic shock will cure to a much weaker strength.
Joggle Joint A method of jointing construction which is no longer recommended. It is
best described as a joint where one piece of stone is let into another,
similar to a carpentry mortise and tenon joint.
Lawn Memorial A jointed memorial with an upright stone fitted to the back of a base stone.
This type of memorial is often between 600mm (2’) and 1200mm (4’) in
height and is a more modern design often found in abundance on lawn
sections of British cemeteries.
Lock Down System A mechanical system used to ‘bolt’ (or lock-down) a memorial base to the
foundation. A number of approved lock-down systems are currently in use
by Memorial Masons.
Memorial Mason A tradesperson responsible for installing memorials.
Monolith memorial One-piece memorial buried between 25% and 35% into the ground. It is
always advisable to fit the memorial into an appropriate "shoe" foundation.

General Health & Safety for the Memorial Mason
These final notes have been designed and produced to give a simple, yet none-exhaustive, list of General Health & Safety subjects ~ some with ‘Internet URL locations’ ~ where the memorial mason can easily source further, more detailed, official information if required. The Health & Safety Executive http://www.hse.gov.uk/
The HSE is the Government Department with the responsibility of providing and monitoring a robust framework for work place health and safety in Great Britain.
For the memorial mason ‘the work environment’ means both working in the masonry workshop or out on-site in the cemetery or churchyard.
The Health & Safety at Work Act (1974) considers the foremost and primary responsibility of an employee is that of ‘ensuring their own safety and that of others’.
Risk Assessment http://www.hse.gov.uk/pubns/indg163.htm
Part of managing the H&S of your business must be control risks in your workplace.
To do this you need to think about what might cause harm to people and decide whether you are taking reasonable steps to prevent any such harm occurring.
This is known as Risk Assessment and it is something that you are required by law to carry out.
PPE (Personal Protective Equipment) http://www.hse.gov.uk/toolbox/ppe.htm
PPE is the generic term for equipment and/or clothing that will help to help to protect the user against any health or safety risks in the work place.
Employers have duties concerning the provision and use of PPE in the workplace and employees have a duty to use and store it PPE correctly.
Correct PPE storage is very important so it’s always fit for use.
RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) http://www.hse.gov.uk/riddor/
RIDDOR puts duties on employers, the self-employed and the people in control of work premises to report certain serious workplace accidents, occupational diseases and specified dangerous occurrences (sometimes known as near misses) to the HSE.
COSHH (Control of Substances Hazardous to Health) http://www.hse.gov.uk/coshh/
COSHH covers substances that are hazardous to health. They can take many forms such as chemicals, fumes, dust, vapours, gases, etc. plus mixed but unused cement and unused marble, stone and granite cleaning chemicals.
Note: If any packaging displays any of the many COSHH Hazard Symbols then the contents is classed as a ‘Hazardous Substance’.
PUWER (Provision and Use of Work Equipment Regulations) http://www.hse.gov.uk/work-equipment-machinery/puwer.htm
PUWER concerns anyone with responsibility for the safe use of work equipment.
It places duties on people and companies, who own, operate or have control over work equipment.
PUWER also places responsibilities on businesses and organisations whose employees use work equipment, whether owned by them or not.

LOLER (Lifting Operations & Lifting Equipment Regulations) http://www.hse.gov.uk/work-equipment-machinery/loler.htm
The LOLER regulations protect everyone who uses lifting equipment in the workplace.
It covers a wide range of lifting equipment such as cranes, fork lifts, gantry's, hoists, etc. and also includes lifting accessories such as chains, slings, webbing and Lewis pins.
LOLER also requires that all equipment used for lifting is fit for purpose, appropriate for the task, suitably marked and, in many cases, subject to statutory periodic 'thorough examination'.
IMPORTANT: Checking Tools & Equipment
Whenever you use any tool or piece of equipment you MUST carry out a thorough ‘before and after’ operation check.
For example: A hammer drill - check the plug and cable for splits or cuts and check the body is not cracked, damp or damaged, check the drill bit is not cracked, etc.
It is equally important to carry out the same checks in reverse before its item is put away.
Manual Handling http://www.hse.gov.uk/msd/manualhandling.htm
Only lift manually if there is no alternative ~ always ask for help wherever possible.
If none is available, use a lifting aid such as a sack truck or a hydraulic pump-up truck.
If you have to lift alone, make sure route is planned, free from obstacles and any loads are handled with a straight back using your legs to provide the lifting force as these are your strongest muscles and do not under any circumstances ‘lift and twist’.
Never, ever abuse your back!
Slips, Trips and Falls http://www.hse.gov.uk/slips/
These are the most common form of hazard causing accidents.
Be aware of their causes and wear suitable footwear and clothing.
Carry out a visual risk assessment and put suitable control measures in place before you begin any practical work.
Define your working area, keep it tidy and don’t leave any tools or equipment lying about for anyone to trip over.
Always remember the time honoured Health & Safety maxim, ‘A tidy site is a safe site!’
Be aware of the possibility of loose memorials or any suspect brickwork nearby.
Weather Conditions http://www.hse.gov.uk/logistics/slips-trips-bad-weather.htm
Sometimes we all have to carry out work in cold, wet or hot weather.
Some types of stone, such as all polished granite for example, can be extremely slippery when wet so always wear suitable gloves whenever necessary.
Multiple clothing layers help keep out the cold and water proof clothing will help keep you dry.
In very hot weather carry a bottle of water to help prevent dehydration and sun blocker to prevent any sun damage to your skin.
Broken Glass
Broken glass can be lethal ~ it is usually broken glass flower vases, jam jars, etc.
Always have a check around the working area before starting work - beware of ‘long grass areas’ which may hide broken glass.
Always use suitable gloves to protect the fingers and knee pads to protect the knees.
Be very careful to check the ground carefully before carrying out a task.

Work Equipment http://www.hse.gov.uk/pubns/indg291.htm
There is little point considering carrying out a task unless you have the correct tools and equipment.
They must be serviceable, in good condition and generally ‘fit for purpose’.
Carry out a quick visual check to ensure all is safe to use and a power check to ensure all is in working order before leaving the workshop.
Any defects should be immediately reported to the management for their attention.
First Aid http://www.hse.gov.uk/firstaid/
H&S state that it is mandatory to have a correctly stocked First Aid Kit in the masonry workshops.
Be aware that many items have a ‘use before’ date.
It is also deemed ‘Best Practice’ to carry a portable Emergency First Aid Kit in any company vehicles.
Perhaps one of the most important items of First Aid equipment out on-site could be a mobile phone to summon help in the case of an emergency!
Members of the Public
In a workshop environment you can pretty well control foot traffic such as visiting customers however, a cemetery is a public place where people, particularly children, my walk near, or even through, your own working area.
If possible, clearly define your working area with a sign or some road cones and always be polite and answer any questions the public may ask in a courteous and professional manner.
Vehicles
We are all aware of Funeral Cortèges in cemeteries and churchyards, and of course members of the public generally use the cemetery’s internal roadways, so everybody must be constantly aware of them.
In addition to the public’s vehicles, cemetery vehicles are very often moving about on-site.
All this noise and movement will have an effect the working environment so the mason must be continually aware of his surroundings ~ this is known as a ‘Dynamic Risk Assessment’.
Drug Paraphernalia http://www.hse.gov.uk/alcoholdrugs/drugs.htm
Sadly, drugs, and therefore, drug paraphernalia are part of our lives on the 21st century.
This paraphernalia could include discarded syringes, razor blades, small spoons, etc.
Do NOT touch anything like this which causes you to be suspicious and, if you are in any doubt whatsoever, contact the Cemetery Management, the Burial Authority or the Police.
Control of Exposure to Silica Dust http://www.hse.gov.uk/pubns/indg463.htm
Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete.
In the workplace these materials create dust when they are cut, sanded, or carved, etc.
Some of this dust may be fine enough to breathe deeply into the lungs causing serious harm to health.
